Travel eSIM Provider Comparison: Airalo vs Holafly vs Nomad vs Saily and More

You already know what to look for in a travel eSIM — coverage network quality, data volume, validity period, pricing model, and activation method. If you have not covered those foundations yet, start with How to Choose a Travel eSIM: 5 Key Criteria before continuing here.

This article takes the next step: applying those criteria to the actual providers available to you. Each provider below has a distinct profile — different strengths, coverage approaches, and plan structures. The goal is to give you an honest picture of each so you can narrow down to two or three candidates, then use SimFinder Travel to compare their current plans for your specific destination.

Specific prices are not included in this article. Plan pricing changes frequently, and any number published here will become outdated. All price comparisons are available in real time through SimFinder Travel.

Major Travel eSIM Providers at a Glance

The table below summarizes the providers covered in this article. All data is sourced from provider records in SimFinder’s database.

Provider Profiles

Airalo

Airalo operates as a marketplace for travel eSIMs — rather than selling only its own plans, it aggregates plans from multiple local provider partners around the world. This model gives Airalo broad destination coverage and a large number of plan options among consumer travel eSIM stores. The tagline on SimFinder’s records describes it as the “World’s First eSIM Store,” reflecting its early entry into the category.

The marketplace structure has a practical advantage for travelers: you can often find a country-specific plan backed by a named local carrier, which tends to deliver better network quality than plans routed through a single international hub. Before purchasing, confirm which local carrier the specific plan uses for your destination.

Airalo’s app and website support an extensive range of languages, making it accessible to travelers across most major language markets. Multi-country and regional plans are available alongside single-country options.

Best for: Travelers who want a broad selection of country-specific plans in one place, travelers who need support in a less common language, and first-time eSIM buyers who prefer a large platform with established customer service.

Holafly

Holafly’s market position centers on unlimited data plans. Rather than selling fixed data packages, Holafly’s primary offering is plans with no data cap — travelers pay for a set number of days rather than a specific gigabyte amount. This removes the anxiety of watching a data balance during a trip.

The trade-off is the fair-use throttle that applies after the daily high-speed threshold. Once that daily limit is reached, speeds drop significantly for the remainder of the day. This throttled speed is generally sufficient for messaging and light browsing but not for continuous video streaming or large uploads. Check the specific plan’s fair-use policy before purchasing — the daily threshold varies by plan and destination.

One important note: most Holafly plans are data-only. They do not include a local phone number for voice calls or SMS. For calls, you will need a VoIP app over the data connection, and for SMS-based authentication codes, keeping your home SIM active in a dual-SIM setup is the reliable approach. For more on managing calls and SMS while traveling, see Your First Travel eSIM.

Holafly supports 20 languages and offers both single-country and regional multi-country plans.

Best for: Travelers who use a lot of data and prefer not to track a balance, remote workers who plan moderate video calls but not extended streaming, and travelers who want a straightforward per-trip pricing model.

Nomad

Nomad covers 200+ destinations with single-country and regional plans. It presents itself as a direct provider with a clean, uncomplicated purchasing experience — the plan catalog is focused rather than exhaustive, and pricing information is presented clearly at each step.

Tethering is supported, making Nomad a workable option for travelers who want to share data from their phone with a laptop or tablet. Multi-country plans are available for travelers crossing multiple borders on a single trip.

Nomad’s app and website support 13 languages, including English, Japanese, Korean, Chinese, Thai, Vietnamese, German, French, Spanish, Portuguese, Italian, and Indonesian.

Best for: Travelers who want a direct purchasing experience without navigating a large marketplace, users comfortable with a focused plan catalog, and travelers in Asia who prefer multilingual support in regional languages.

Saily

Saily is developed by the team behind NordVPN, a company established in the cybersecurity space. Its positioning combines travel eSIM functionality with pricing that sits at the more affordable end of the market compared to some competitors.

The connection to NordVPN’s development team is primarily a credibility signal rather than a technical feature difference — Saily functions as a standard travel eSIM provider with single-country and regional plans, tethering support, and app-based management. It does not bundle VPN functionality into eSIM plans.

Saily supports 14 languages including English, Japanese, Korean, Chinese (Simplified and Traditional), German, French, Spanish, Portuguese, Italian, Czech, Lithuanian, Polish, and Dutch.

Best for: Budget-conscious travelers who want a recognizable brand with a security-focused company background, and travelers in European markets where Saily’s supported languages are a good fit.

aloSIM

aloSIM covers 200+ countries and territories with both single-country and regional plans. Tethering is supported across its plan catalog. The provider’s app supports multiple languages; specific language coverage varies by app store listing and region, so verify support for your preferred language before purchase.

aloSIM’s app is available on both iOS and Android, and plan management — including purchasing additional data — is handled through the app.

Best for: Travelers heading to destinations in the Middle East, South Asia, or less common regions where some providers have limited coverage, and travelers who want a provider focused on fixed-data single-country plans across a wide country range.

Ubigi

Ubigi is operated by Transatel, a subsidiary of NTT Communications since 2019 (NTT Group). This corporate backing gives Ubigi infrastructure stability less common among newer travel eSIM entrants. Ubigi has been in the eSIM market longer than most consumer-facing providers, with integrations across several connected-car manufacturers (BMW, MINI, Toyota, Stellantis, Jaguar Land Rover) and Apple — Ubigi is selectable from an iPad’s Settings → Cellular Data → Add a New Plan menu, enabling plan purchase directly from the device without installing the Ubigi app.

A distinguishing feature of Ubigi’s account model is long eSIM profile validity: the profile remains active for up to 18 months of inactivity without being removed. This suits travelers who take multiple international trips over a year without wanting to reinstall the profile each time.

Ubigi supports multiple languages and offers single-country, regional, and global plan options with tethering.

Best for: iPad users who want direct plan purchase from device settings, travelers who take multiple trips across a year and want their eSIM profile to remain active between trips, and travelers who prefer a provider with established carrier-level infrastructure behind it.

GigSky

GigSky offers single-country, regional, and global plans with a focus on broad international coverage. As a full MVNO, GigSky maintains roaming agreements with 400+ mobile networks across 190+ destinations. A notable differentiator is support for cruise ships and in-flight connectivity plans, which most travel-eSIM providers do not address.

Tethering is supported, and GigSky’s plan catalog includes global options suited to travelers visiting multiple regions on extended trips. The provider offers multilingual app support; verify specific language availability on the App Store or Google Play listing before purchase.

Best for: Travelers visiting multiple continents or undertaking extended international travel, users who want global plan flexibility with carrier partnership coverage in key markets.

How to Match a Provider to Your Trip

The profiles above give you the “what” for each provider. This section maps trip types to which providers are worth comparing first.

Single-country trip of one to two weeks (Europe, Asia, or Americas) Start with Airalo and Nomad for single-country plan options. Both support a wide range of destinations and display the local carrier partner for each plan, which lets you evaluate network quality before purchasing. Compare current plan pricing and data amounts on SimFinder Travel.

Unlimited data for remote work or frequent video calls Holafly’s unlimited plans are the most direct fit. Confirm the daily high-speed threshold for your destination plan before purchasing — if the threshold is too low for your usage pattern, a large fixed-data plan from Nomad or Airalo may serve you better without unexpected throttling.

Multi-country trip crossing three or more borders Evaluate Airalo’s and GigSky’s regional or global plans, and check Nomad’s multi-country plan coverage. Compare which plan covers all your specific destinations — not just the region name — and check the listed network partner for each country included. Ubigi is also worth checking for its global plan if the trip spans multiple continents.

Extended stay or multiple trips over a year Ubigi’s eSIM profile stays active for up to 18 months without a top-up, which suits travelers who alternate short trips over several months without wanting to reinstall the profile each time. Check current plan terms for your region before purchase.

First-time eSIM user who wants accessible customer support Airalo’s broad multilingual support and established platform make it an accessible starting point for first-time users. A large platform with documented support processes reduces friction if something goes wrong. Read Your First Travel eSIM before purchasing to understand what to expect during installation.

Travelers prioritizing cost over brand Compare Saily and aloSIM alongside Nomad for the destination in question. Pricing varies by destination and plan length, so use SimFinder Travel to compare current rates rather than assuming a fixed ranking. Per-gigabyte cost is the metric to calculate for fixed-data plans.

Red Flags to Avoid

Not all travel eSIM providers operate with the same transparency. When evaluating any provider — including ones not covered in this article — watch for the following:

Coverage claims without named network partners A trustworthy provider lists the local carrier partner for each destination plan, not just a shaded map. If the provider’s website shows only a colored map with no mention of which network your device will connect to, you cannot verify coverage quality. Ask before purchasing, or choose a provider that discloses this information clearly.

5G claims without verifiable partner networks 5G availability in travel eSIM plans depends entirely on whether the local partner network in your destination supports 5G and whether the eSIM plan explicitly enables it. Vague 5G branding without a named local carrier offering 5G service is a marketing claim, not a functional guarantee. If 5G matters for your trip, confirm the specific partner network and its 5G footprint at your destination.

Unclear refund and top-up policies Before purchasing, verify two things: whether you can get a refund if your trip is cancelled before you activate the eSIM, and whether you can purchase additional data mid-trip without buying an entirely new plan. Providers with unclear or restrictive policies on both points create unnecessary friction if your plans change.

No app-based management Managing a travel eSIM — tracking data usage, purchasing top-ups, contacting support — is significantly easier through a provider app than through email or a website alone. If a provider offers no app, plan management during the trip becomes more cumbersome. All seven providers profiled in this article offer app-based management.

Unusually low pricing without explanation Pricing that is substantially lower than comparable plans from established providers warrants scrutiny. Travel eSIM providers incur real network costs. Plans priced far below market norms sometimes indicate limited local network access (routing through lower-quality international hubs), very restrictive data throttling terms, or simply inaccurate advertised prices. Verify the terms carefully before purchasing.
